# Service bulletin 9004230

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

LAMP, Center High Mounted Stop \(CHMSL \- Cargo lamp\) For concern of water leak intrusion at CHMSL lamp: Before CHMSL lamp removal, please check for proper CHMSL installation. Verify that CHMSL harness is well hidden \(not visible\) into the cabin and not trapped between lamp and cabin. If harness is trapped, take a picture and verify seal foam also has a harness mark. Add this comment into narrative. Please call FCA Redacted Content prior to replacing the component \(if needed\). If no response in 15 minutes, proceed with repair.
